What is the total energy of a body weighing 60 kg if it has a potential energy of 120 J and moves at a speed of 4 m / s?

To find the value of the total energy of the specified body, we use the formula: En = Ek + Ep = m * V ^ 2/2 + Ep.

Variables and constants: m – mass (m = 60 kg); V is the speed of the specified body (V = 4 m / s); Ep – potential energy (Ep = 120 J).

Calculation: En = m * V ^ 2/2 + Ep = 60 * 4 ^ 2/2 + 120 = 600 J.

Answer: The total energy of the specified body is 600 J.
